This optimizer transformation doesn't look right for projected columns like ``` create table t1(v1 int); insert into t1 values (null); select v1=v1 from t1; -- Should return `NULL`, but get `False` ``` However it makes sense if it is only applied on filter expressions. -- This is an automated message from the Apache Git Service.
